Reconfiguration Of Small Network

Hi All,

Currently we have the following network setup:

3 Servers (2 Physical 1 Virtual)

2 Physical Servers:

ONE running 2008R2 (PDC) and being the AD DS, RDP server and DNS server AND the Hyper V host
TWO running 2012R2 being a DC and also storing backups of 2008R2 server state.
VIRTU running 2008R2 and being hosted on server ONE. Users all RDP to this server and it provides word, excel etc and our own software that runs in IIS.

We're having problems with the VM crashing a lot. Things have settled as we have gone through resolving DNS and other issues but we have been advised to upgrade to 2012R2.

So before agreeing on a way forward, I'd really appreciate some input on the best set up.

The idea is:

Upgrade server ONE to 2012R2 and then create a VM of it (call it VMONE).
Remove all roles on ONE except RDS and Hyper V
Install VMONE on ONE as the PDC with AD DS, DNS etc.

Happy to add additional physical servers if required. The physical server ONE is a dual CPU, 36GB RAM server. Server TWO is a single CPU 8GB ram server that has very little load other than backup services and DC role.

Any suggestions gratefully received.

I would do the following :

Migrate all roles except Hyper V to Virtual Server's on the 2012( You would need to install Hyper V) - taking best practises as seen above into account. Ideally i always try to seperate major roles each to their own VM. The advantages hyperv 2012 has over 2008 is big - go read up on it.

I would then upgrade the 2008 to 2012 and install Hyper V.

Lastly I would setup failover clustering on both 2012 servers so that the virtual servers have redundancy between the servers.

Lastly you can divide all your vm's between the 2 servers to best utilize hardware.

Thanks for the all the suggestions. You're right this isn't my area of expertise. But after the mess the IT guys we trusted this to caused, I'm using experts exchange as a way to identify the best way forward, so at least I can tell when I'm speaking to someone who knows what they ARE doing!

Our biggest problem is the server is in (almost) constant use and taking it offline we only have a small window (5 hours) to do.

I should also mention that the network is only 5 users all remote desktop (using zero clients), not sure whether that makes any difference?

No we don't have multipoint. We have HP Zero clients which connect to the server via RDP.

I'm searching for managed options as I type... will update this thread.

Thanks
In terms of licensing costs, so that I can budget our requirements, what versions of windows server 2012R2 would be suitable for each role?

So for example, we already have one machine with 2012R2 essentials that acts as physical DC and one copy (license) of 2012R2 standard with 5 cals that is yet to be installed in any server (and gives I believe 2 VMs).

Would essentials be sufficient for separate RDS server role? Thanks in advance
